Project Spartan(Edge)のHTML5の準拠度をチェックする

Project Spartanの今のHTML5準拠度ってどれくらいなのか。ということでHTML5 Testを実施し、他のブラウザと比較してみることにした。

https://3usfiw.dm2301.livefilestore.com/y2pS8aW7eMo7e6MqVO2GMk7AfPQ4C1BKUchLpNTWBgwrZ714vjW0OCrIqlI9bgW7GgewKPeR7LaEj3u6hIWQ1TXlM8byUtWAss6lLWDcgXaqCPC3TMHhjLwMbvQ2ESlPfwKMLG_x2JuzVOIwpn1jaMvKDlJ-lx_PLVS9QdAJ-AeOVI/042901.png?psid=1

総合

まずは総合ポイント。満点は555ポイント。

項目 Spartan Internet Explorer 11 Chrome 39 Firefox 35
総合 390 348 523 445

IE11よりは良いが、まだまだといったところ。どこでポイントを落としているか各カテゴリで見ていくことにする。

Semantics

Parsing rules (5点満点)

項目 Spartan Internet Explorer 11 Chrome 39 Firefox 35
小計 5 5 5 5
<!DOCTYPE html> triggers standards mode Yes ✔ Yes ✔ Yes ✔ Yes ✔
HTML5 tokenizer Yes ✔ Yes ✔ Yes ✔ Yes ✔
HTML5 tree building Yes ✔ Yes ✔ Yes ✔ Yes ✔
Parsing inline SVG Yes ✔ Yes ✔ Yes ✔ Yes ✔
Parsing inline MathML Yes ✔ Yes ✔ Yes ✔ Yes ✔

MathMLってインラインで書けるのね。ついさっき知ってしまった。ただ上記の結果はブラウザがSVGとMathMLのインライン記述をパースできればOKとしているようで、実際描画されるかどうかまでは検証していないようである。よってこの項目はポイントはつかない。
SVGは大丈夫だろうけれどもMathMLはどうなのか。ちょっとMathMLのテストを実行してみたけど描画されなかった。今のところFirefoxとSafariがMathMLをサポートしているようである。この項目はサポートしていてもポイントが付かない。

Elements (30点満点)

項目 Spartan Internet Explorer 11 Chrome 39 Firefox 35
小計 20 16 26 21
Embedding custom non-visible data Yes ✔ Yes ✔ Yes ✔ Yes ✔
New or modified elements

Text-level semantic elements Partial ○ Partial ○ Partial ○ Partial ○
Interactive elements No ✘ No ✘ Partial ○ No ✘
Global attributes or methods
hidden attribute Yes ✔ Yes ✔ Yes ✔ Yes ✔
Dynamic markup insertion Yes ✔ Yes ✔ Yes ✔ Yes ✔

このセクションでは10ポイント落としている。IE11のレベルからそう変わっていないようだ。まだ手を付けていないのか。

  • Grouping content elementsの項目では<ol>reversed属性がサポートされていない。これは番号付きリストを逆順に表示するものだ。
  • Text-level semantic elementsの項目では<a>downloadping属性をサポートしていない。さらに<time>エレメントも未サポートである。これはちょっと意外である。
  • Interactive elementsの項目では<details><summary><menu>type="toolbar"/type="popup"<dialog>が未サポートである。ただまあこのカテゴリのエレメントは他のブラウザもあまり実装が進んでいない。

*この項目でSpartanは大きくポイントを落としている。IE11とポイントが同じところを見るとまだ手をつけらていないように見える。こういうところを見るとSpartanはIE11をベースに改良アプローチで作られているのかな?レンダリングエンジンは新たに書き起こしたようだけれどもね。

Microdata(0点満点)

項目 Spartan Internet Explorer 11 Chrome 39 Firefox 35

MicrodataはRDF-Liteに移行していくのだろう。なのでサポートされていてもポイントはつかない。

まとめ

まとめるほどの知識はないが無理やりまとめると、HTML5 TestでStableとなっている機能についてはほぼほぼ、Proposalについてはまあまあ、Experimentalについては未実装という感じである。Experimentalなんてころころ変わるから様子見かもしれないね。Windows 10のリリースまでには日にちがあるのでこれがどこまで実装されるのか。個人的にはWeb Audioが実装されたのがうれしいね。VP8/VP9の実装がなされるのかも見ものであるが。

ただSpartan自体はまだまだ。なんかおかしな挙動をするしね。

最後に

SunSpider BenchmarkによるJSの速度比較を載せておく。私のマシンでは驚きの結果が。。ほんとかね。。
